REEL AND RAKE APPARATUS FOR COMBINES Filed 001;. 2a, 1944 2 Sheet-Sheet 2 Patented Nov. 16, 1948 REEL AND RAKE APPARATUS FOR COMBINES Houston N. Irvine, Burlington, Iowa, assignor to J. I. Case Company, Racine, Wis., a corporation of Wisconsin Application October 28, 1944, Serial No. 560,779
My invention relates to a reel and rake apparatus for combines.
' and also as a rake for feeding the material, after it has been cut, upwardly and rearwardly to the threshing mechanism, thereby avoiding the necessity of the usual canvas conveyor in a combine header.
In the drawings, in which an embodiment of my invention is shown,
Figure 1 is a side elevational sectional view substantially on the line II of Fig. 2 of a combined reel and rake apparatus;
Fig. 2 is a front View of this apparatus, parts being omitted and parts being shown in section; and
Fig. 3 is a somewhat diagrammatic plan view showing a portion of the header, the drawbar and a control lever.
Referring to the drawings in detail, the con struction shown comprises an upwardly and rearwardly inclined chute or deck I which is pivotally attached at I to the combine in such a way that its front end is floatably supported by shoes 2 which may rest on the ground as the combine is drawn along, the chute I oscillating about the pivotal attachment I as the shoes 2 move up and down over uneven ground, a sickle 3 carried by this chute for cutting the grain, a flexible endless belt-like reel and rake member 4 supported by said chute, and mechanism for driving and supporting the belt-like member 4 and raising and lowering the front end thereof.
The belt-like member 4 as shown comprises a pair of sprocket chains 5 connected together by transversely extending channel bars 6, which channel bars engage the material a to be cut and hold it against the sickle and after the material is cut feed the material upwardly and rearwardly along the chute I to deliver it to the feed auger 8 which feeds it to the cylinder of the threshing apparatus. Each of the sprocket chains 5 is supported and guided by means of a rotatable front sprocket wheel 9, a rotatable rear drive sprocket wheel I0, and a rotatable idler sprocket II.
In order to provide for the up-and-down adjustment of the front sprocket wheels to take care of grain of diiferent heights, they are mounted on a transversely extended shaft I2, the ends of which are carried by bearings I3 on adjustable bell crank levers I 4 pivotally mounted at I5 on 3 Claims. (Cl. 56-219) the sides I6 of the chute. Sprin means I I are provided secured at I8 to the downwardly extending arms I9 of the pivoted levers I4 and secured at 20 to the under side of the chute, urging'the front ends of the levers I 4 and the sprocket wheels 9 carried thereby upwardly. The distance which the spring means II can force the sprockets 9 upwardly is limited by the idler sprockets II. In order to provide for the raisin and lowering movement of the front end of the endless beltlike member 4, the idler sprockets II are made adjustable longitudinally of the chute from the position shown at A to the dotted-line position shown at B. As the sprockets are moved downwardly and forwardly, the front sprockets 9 are lowered and at the same time the lentgh of the portion of the flexible member extending parallel to the bottom of the chute I is increased.
To provide for this sliding motion of the bearings 2I which carry the sprocket wheels I I they are slidably mounted in guides 22 extending longitudinally in the sides I5 of the chute, and cables 23 are secured to these sliding bearing brackets 2|, respectively, which run over pulleys 24 adjacent the lower end of the chute and thence rearwardly to pulleys 25 at the upper rear end of the chute. Rotation of the pulley 25 is effected by means of a lever 25 pivotally mounted on the drawbar 21 within easy reach of the tractor operator. The transmission from the lever 26 to the pulley 25 and hence to the bearings 2I carrying the sprocket wheels II comprises a pulley 28 of smaller diameter than the pulley 25 mounted on the same shaft 29 on which the pulley 25 is mounted, and a cable 39 secured to thispulley, passin thereover, extending forwardly and secured to the lever 25. The design is such that a full movement of the lever 26 will cause the bearings 2! to travel the full length of the guides 22. It will be noted that the pulley 28 is smaller than the pulley 25 so that the cable 23 will travel a greater distance than the cable 36. The driver of the tractor, by means of the lever 26, may in stantly raise or lower the effective height of the rake as may be necessary to suit conditions encountered at the moment. A latch and quadrant 3| may be provided for holding the lever in adjusted position. As the lever 26 is moved forwardly, the sprockets II will be drawn downwardly and forwardly against the resisting action of the sprocket chains 5 and of the spring means I1 which hold the sprockets 9 as far up as the sprockets I I will permit.
In use, if tall grain is to be cut, the lever 26 will be operated to allow the sprocket wheel II to rise to the full-line position shown at A in Fig. 1, in which the cross channels or slats 6 on the endless member will properly engage the tall grain adjacent the upper ends of the stalks and bend it rearwardly, holding it in engagement with the sickle. If the material to be cut is relatively short, the lever may be operated-to draw the sprockets il l down to the dotted-line position sh'own at B in Fig. 1, in which the slats on the endless member will engage the grain to be cut adjacent the upper end of the stalk and bend it over and hold it against the sickle. In this-lowering movement of the sprocket wheels, the idler sprockets have been moved downwardly'and =forwardly to the position shown in'sdotted dines, so that the portion of the endless member which extends parallel to the chuteordeck is lengthened in a forward and downward direction in position to engage the grain as soon as it has been cutand carry it upwardly and rearwardly.
' Further modifications will be apparent-to those :skilled in the art and it is desired, therefore, that the invention be limited only by the scope of the :appended claims.
Having thus described my invention, what I claim'and desire to secure by Letters Patent is:
